 /**
  * A general-purpose dialog that hosts a form. Clients should extend the class
  * and override <code>createFormContent(IManagedForm)</code> protected method.
  * <p>
  * Since forms with wrapped text typically don't have a preferred size, it is
  * important to set the initial dialog size upon creation:
  * <p>
  *
  * <pre>
  * MyFormDialog dialog = new MyFormDialog(shell);
  * dialog.create();
  * dialog.getShell().setSize(500, 500);
  * dialog.open();
  * </pre>
  *
  * <p>
  * Otherwise, the dialog may open very wide.
